How order affects the sign test.
In carrying out the sign test, the order in which the subject receives the treatments may be important. We examine Gart's test and show it is equivalent to a score test under a product binomial model. If equal numbers of subjects receive each treatment order, then we suggest our form of Gart's test rather than the sign test should be used routinely.
